As promised, today Pottermore released the first few chapters of Harry Potter and the Prisoner of Azkaban to all users.

We love to go through the chapters as soon as they open and share a breakdown of what you’ll find. In all, Pottermore released seven chapters which’ll leave you browsing through for a bit.

It’s important to know that before you advance into Prisoner of Azkaban, first you will have to have all of the items on your shopping list in Chamber of Secrets. To do this, head to Diagon Alley (link at top of Pottermore towards the left) and buy the items on the list (you’ll see a link to view the items you need).

Chapter 1: Owl Post

– Read Ron and Hagrid’s birthday letters to Harry, collect a couple of items.

Chapter 2: Aunt Marge’s Big Mistake

– New from J.K. Rowling: Aunt Marge

Sample: “Marge is a large and unpleasant woman whose main interest in life is breeding bulldogs. She believes in corporal punishment and plain speaking, which is what she calls being offensive. Marge is secretly in love with a neighbour called Colonel Fubster, who looks after her dogs when she is away. He will never marry her, due to her truly horrible personality. This unrequited passion fuels a lot of her nasty behaviour to other people.”

Chapter 3: The Knight Bus

– New from J.K. Rowling: The Knight Bus

Sample: “The Knight Bus was so-named because, firstly, knight is a homonym of night, and there are night buses running all over Britain after normal transport stops. Secondly, ‘knight’ has the connotation of coming to the rescue, of protection, and this seemed appropriate for a vehicle that is often the conveyance of last resort.

The driver and conductor of the Knight Bus in ‘Harry Potter and the Prisoner of Azkaban’ are named after my two grandfathers, Ernest and Stanley.”

Chapter 4: The Leaky Cauldron

– Collect a couple items

Chapter 5: The Dementor

– Nothing

Chapter 6: Talons and Tea Leaves

– New from J.K. Rowling: Sir Cadogan

Sample: “It is widely believed in wizarding circles that Sir Cadogan was one of the famous Knights of the Round Table, albeit a little-known one, and that he achieved this position through his friendship with Merlin. He has certainly been excised from all Muggle volumes of King Arthur’s story, but wizarding versions of the tales include Sir Cadogan alongside Sir Lancelot, Sir Bedivere and Sir Percivale. These tales reveal him to be hot-headed and peppery, and brave to the point of foolhardiness, but a good man in a corner.”

– New from J.K. Rowling: Professor Kettleburn

Sample: “Kettleburn was a loveable if eccentric man and his continuing employment at the school was evidence of the great affection in which staff and students held him. He finished his career with only one arm and half a leg. Albus Dumbledore presented him with a full set of enchanted wooden limbs on his retirement, a gift that had to be replaced regularly since, because Kettleburn’s habit of visiting dragon sanctuaries in his spare time meant that his prosthetics were frequently set on fire.”

Chapter 7: The Boggart in the Wardrobe

– New from J.K. Rowling: Boggarts

Sample: “Famous Boggarts include the Old Boggle of Canterbury (believed by local Muggles to be a mad, cannibalistic hermit that lived in a cave; in reality a particularly small Boggart that had learnt how to make the most of echos); the Bludgeoning Boggart of Old London Town (a Boggart that had taken on the form of a murderous thug that prowled the back streets of nineteenth-century London, but which could be reduced to a hamster with one simple incantation); and the Screaming Bogey of Strathtully (a Scottish Boggart that had fed on the fears of local Muggles to the point that it had become an elephantine black shadow with glowing white eyes, but which Lyall Lupin of the Ministry of Magic eventually trapped in a matchbox).”
